Dear Takashi:
Hans de Goede (on cc:) hits a problem when snd-usb-audio breaks with:
"USB device is in the shutdown state, cannot create a card instance".
This is how the place looks:
chip = NULL;
for (i = 0; i < SNDRV_CARDS; i++) {
if (usb_chip[i] && usb_chip[i]->dev == dev) {
if (usb_chip[i]->shutdown) {
snd_printk(KERN_ERR "USB device is in the
shutdown state, cannot create a card instance\n");
goto __error;
}
chip = usb_chip[i];
break;
}
}
The code looks broken to me, because dev at this time is a new device
structure, freshly allocated. You cannot compare it with an old instance,
and I don't know why you would want to.
Unfortunately (for fortunately), I have zero clue about the way ALSA
works, specifically rules for snd_device_ops.dev_free, so I am asking
you to look at this problem.
Yours,
-- Pete
